by Athul P Kurian – Do you like to be a social chameleon in life?
Just take a look at this. During my field work in Hesaraghatta, I found something interesting. Chameleons hunt with a lightning fast tongue, and take on the colour of what they touch, which helps them to blend into their surroundings. The colour-changing skin is also used for communication. The layer of pigmentary cells in the skin consists of nanosacle crystals that are arranged in a triangular lattice. The lattice can be tuned to alter the spacing between the crystals, which, in turn, affects the colour of light that the lattice of crystal reflects. You can read about this fascinating process here.
